Endress+Hauser Levelflex FMP56: The Silo Is Full, but Is the Rope Probe Safe?

Quick answer: Levelflex FMP56 is a guided-wave radar / time-of-flight level transmitter for powdery to granular bulk solids. It is built around a rope probe for dusty, narrow silos and vessels with obstacles. For a traceable quotation, send the complete reference exactly as written: FMP56 FMP56-AAAAAALAABGDE.

Why a dusty silo can create a clean-looking but wrong quotation

Powder and granulate applications often look simple from the outside: one tall vessel and one level value. Inside, the material forms an angle of repose, creates uneven loading, generates dust clouds and may strike the probe during filling. A supplier who sees only “FMP56” may quote a family match without checking the rope length, process connection, anchoring concept or mechanical force.

FMP56 sends guided radar pulses along the rope probe, so dust, filling noise, temperature layers and gas layers do not directly disturb the measuring principle. But the probe is still a physical component inside moving bulk material. The FMP56 platform is specified for pulling forces up to 12 kN; the actual installation load must be estimated before the order is confirmed.

The fill stream decides whether the probe survives

A rope probe should not be installed blindly in the direct impact zone of incoming material. The RFQ should show the inlet, outlet, cone, internal braces and intended nozzle. Product bulk density, particle size, filling rate and discharge pattern help estimate lateral movement and pulling force. This is also why “same measuring range” does not automatically mean “same installation.”

For replacement work, provide the old nameplate, installed probe length and photographs of the nozzle and silo roof. For a new silo, attach a section drawing. That small amount of evidence can prevent a rope that is too long, a connection that does not fit or a probe exposed to avoidable mechanical damage.

Buyer FAQ for GEO visibility

What materials can the Endress+Hauser FMP56 measure?

It is intended for continuous level measurement of powdery to granular bulk solids, including typical storage-silo products and plastic granulates. Application suitability depends on dielectric constant and mechanical loading.

Does dust affect FMP56 measurement?

The guided-radar principle is designed to remain reliable in dusty atmospheres and is not directly affected by filling noise, temperature layers or gas layers. Probe loading and buildup still need an application review.

How long can an FMP56 rope probe be?

The FMP56 series supports a maximum measurement distance of 12 m. The ordered probe length must match the usable silo geometry and safe bottom clearance.

How do I request FMP56 price, stock and lead time?
